LOOM SHUTTLE.

Application fi'l'edtFebruaryfi, 1920,-Seria1 No. 355,674; Renewed May 31,1921". Serial No. 473,775.

a citizen of the United States, residing at Fall: River, county of Bristol, CommonwealthofMassachusetts, have invented cer-' tain new and useful Improvementsfin Loom Shuttles, of which the following is a specification.

This invention relates to threading eyes for loom shuttles, and particularlyto an'eye or bushing of porcelain or other hard 'nongroovable material. 'cially adapted-for use with a hardedrawn fillingsuch as silk thread, the tendency of which is to out the usual wire ormetallic Such eyes are espeeye. Although the advantages of a bushing of this character are apparent, one factor which has prevented their general use has been the difii'culty' of properly fastening the bushing in the threadingeye f of the shuttle-- lVhere glue alone is'relied upon, the bushing has been'liabl'e to drop out by reason of, the

glue loosening duringthe run of the shutt le. The varyingconditions of temperature and'humid-ity in the different working room's of the mills also contribute towards this result.

To the end therefore ofprovidinga bushing which willbe positively retained in the threading eye underall conditions of use of the shuttle, and which will;ei'lectively direct the filling into the eye'andjprevent improper escape, thereof" during the run of the shut-; tle, I have devised my'present Invention, the

construction and operation of which,i together with. a selective, embodiment which well illustrates the principles involved, is.

disclosed; in the following specification and the drawings forming a part thereof, throughout which like reference characters are correspondingly applied, and in the drawings: i

Fig. I is a plan view of the threading en of a shuttle equipped with ourinvention.

Fig. II is a longitudinal section thereof on the line II-II, of Fig. III.

Fig. III isa side elevation. r Fig, IV is a transverse section on the line IV-IV of Fig. III, and

Fig. V is a detail view of the bushing removed.

I have indicated at 1 the shuttle body which is provided with the usual bobbin chamber '2, threading eye 3, and threading slots 4 and 5 connecting the bobbin chamber a pair of oppositely disposed longitudinally extending beads or keys 9 and 10 which snugly fit in correspondingly shaped counter bores- 3 of the eye 3 and thus fix the bushing within the shuttle eye. By this construction 7 the cylindrical portion of the bushing above the keys 9- and 10 may fi t; relatively loosely in the bore 3, the. snug fit of the keyslthemsel' ves being relied upon to fix the position of the bushing, If desired, the outer-ordelivery end of the bushing maybe slightly undercut to leave a portion 11 overhanging the bore 7 and serving asa barrier to pre- .ventthe filling from lifting out of the'bore during the run of the shuttle.

"At 'the delivery endof the threading; slot 5 the wood of'the shuttle" adjacent the eye 3 isicutaway as indicated at 12 to provide an upwardly curved passage which extends as a continuation of" the slot 5 and leads the filling upwardly and under the eye guard 13, sothat the filling is laid through the slot 8 into the bore 7'ofthe,bushing 6 front Specification of Letters Patent.

above'in threading. The guard 13 is a si-mple -staple-like member 'set across the delivery end ofthdbushing as beSt'shown in Fig. III, with its pointed legs embedded in thewood of" the shuttle, and between saidlegs, bent toprovide. a relatively downwardly inclined portion 14 overlying the passage 12 adjacent its juncture with the end of the slot 4 and providing a barrier past which the filling twists as it is carried upwardly by the curved adjacent wall of the bushing towards the thread inlet slot 8. The

guard 13 as a wholeassists to prevent improper escape of the thread from the bore 7 of the bushing 6, as-by a direct upward lifting movement, after the shuttle has been threaded.

In assembling, the shuttle is first bored and counterbo'red to provide the eye 3, key

V to span the outer end of the bushing. If desired the' fiat basal portion 6 of ,the

seats 3 and passage 12. The bushing 6 is then inserted endwise through theouter end of the eye 3 with its. key portions, 9,. 10 and 11 seatedin the counter bores 3 and if desired glued therein, after which the staple-like eye guard 13 is driven into the Woodof the shuttle in such manner as bushing may be notched as indicated at 6*,

Fig. V, and a screw 15' set through the -wood of the shuttle from below may enter said notch to assist in retaining the bush- 7 threaded. The opposite wall'at this'end of passage. Q 4s the bushing serves-as a snubbing post past which-thethread from the bobbin'runs in the'threading operation and may be undercut toprovide an overhanging portion 6 effective to prevent the thread from lifting upwardly as it is drawn through the threadingjslot 4. I arious modifications in the form and .con-

'tstructio'nof my device mayobviously be 1nade,'jall without 'departing from the spirit of the-invention, if within the lirnit's of, the

appended claims, o "What I-there-fore claim and desire to se-t cure-.by Letters Patent is:

11. 1A thread conductor for the threading eye-of a shuttle, consisting'of a'basal por tion having ribs along its longitudinal edges 7 effectiveto key the thread conductor in the .shuttle eye and a centrally disposed portion surmon-ntin-g said basaljportionand having a central cylindrical thread passage and a thread inlet slot opening into said" thread 2.- A. thread condu'ctor for the threading eye of a shuttle, consisting of a basal po'rtion" having its longitudinaledges formed 7 as ,ribsefiective to key thethreadiconductor in the shuttle eye and a cylindrical portion surmountingsaid basal portion and having 7 an axial bore and a longitudinally:extend ing thread inlet slot opening into said bore,

the inner end of said cylindrical portion on i one side of said slot "sloping downwardly to meet said basal portion.

3. A thread conductor for the threading eye-ola shuttle, consisting of a basal portion having longitudinally extending ribs effective to key the thread conductor inthe shuttle eye, and a'tubular portion surmount-- ing said basalportion andintersected along its upper edge and substantiallycontinuously from end to end thereof'by a thread inlet slot.

4. A-thread conductor for the threading eye of a shuttle, consisting of a basal portionhaving ribs along its longitudinal edge effective to key the thread conductor in the shuttle eye, said basal portion having a marginal notch for the receptionot' a fao-i tening, and a centrally disposed cylindrical portion surmounting saidlbasal portionand,

having a thread inlet opening.

5. A thread conductor for the threading eye of a shuttle, consisting of a basal por-' tion having oppositely disposed extensions effective to keythe thread conductor in the shuttle eye, and a central portion surmounting said basal portion and disposedcem trally between said extensions thereof and having an axial bore and a thread inlet slot opening into said bore,"the inner end of said central portion at oneside of said slot beingundercut to provide, a snubbin'g surface for vthethre ad. a

6; A thread conductor for the threading" eye of a shuttle,- consisting of abasa]. portion having longitudinally extending ribs effective to key the thread conductor in the i portion surmounting said basal portion and] shuttle eye, and a'centrally disposed tubular providing asubstantially cylindrical thread passage, 'said tubular 'pfortion intersected along its upper edge and substantially con-' tinuously from end to "end thereof: by a thread. inlet slot opening into said thread passage. it is In testimony whereof'I aflix mysignature in presence of two witnesses.
